Quality and Stability of DNA Ladders Shipped at Ambient Temperature

Promega Corporation
Publication Date: March 2019


The testing described in this White Paper explains the methods used to evaluate DNA ladders shipped under ambient conditions rather than gel or dry ice. To replicate the temperatures experienced when shipping DNA markers, ISTA 7D recommendations were used. Then the functional gel analysis and fill volume evaporation tests were performed, comparing the shipped DNA markers to those in inventory. Both testing methods showed no change in DNA marker volume and identical gel analysis profiles.
